Özet:

An X band voltage controlled oscillator with wideband tuning range has been successfully designed and realized. Designed oscillator was designed as planar structure and use only microstrip lines for resonator. Measured free running frequency of this VCO is 9.917 GHz and a 2004 MHz tuning range is obtained with an output power varying from 4.39 to 6.45 dBm. Measured phase noise is between -121.81 dBc/Hz and -110.16 dBc/Hz at 1 MHz offset over the whole tuning bandwidth. Average phase noise value at 1 MHz offset is -117.16 dBc/Hz.
